Mg+I2=MgI2

a. How many moles of iodine, I2 will combine with 5.25 moles of Mg?
b. How many moles of MgI2 is produced by 4.25 moles of magnesium?

c.5.76 moles of magnesium will produce how many grams of MgI2?
d.359 grams of iodine I2 will produce how many moles of MgI2?

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
